Plussy!
Hey kids, it's Plussy, your favorite plus sign, and he's ready to multiply on your TI-83+. What's that, you say? Plus signs are for addition only? You haven't played Plussy. There's a 16x4 grid, and your job is to fill it with plus signs. Only problem is the mean ol' asterisk, who likes to erase the plus signs you make. Not only that, but if you run into him, the game ends! Plussy is the first ever half-way decent non-text game I made with ASCII characters. Originally called Fill 'Er Up. This game uses the [B] matrix, so if you already have a [B] Matrix you like, just go into the code and replace [B] with your next available matrix. Finally finished 2/10/10! Plussy puts the plus in the TI-83+!
